EROEI: Energy Return on Energy Invested. Memorize that phrase, and use it, to help others understand why the future cannot be like the past — unless, of course, the prospect of free energy is just around the corner or is, in fact, already here, just suppressed by the PTB.
Well that may be; meanwhile however, as we wait for the galactics, the whistleblowers, and the inventors to save us, we need to shift from thinking in terms of an “(endless) growth economy” in which we cannot help but fail to realize our impossible goals to a “steady state economy” where we aim for zero waste. Zero. Nothing left over. Everything included. What we call “waste” is food for something, what? We need to find out; let’s explore how this physical, biological, chemical world really works. Let’s investigate — and celebrate — the details of our mysterious mutual interdependency with every living thing.

Every unit of fossil energy we use to do anything else commits us and this planet to a lower standard of living in the future
The New Austerity & the EROEI Squeeze
Although not a single politician or mainstream economic analyst has ever made the connection, the new worldwide austerity in public spending traces to a physical cause, as measured by change in EROEI — energy return on energy invested. This is the ratio between the energy that comes into the global economy and the energy it takes to produce that energy. Worldwide, the average EROEI of oil is down to 20:1 from its original value of 100:1 eighty years ago. This means that our oil-fueled economy simply has less capacity to generate wealth than it did back then, because an increasing share of the energy that used to be dedicated to producing goods and services is being plowed back into securing energy.
Even more troubling than oil’s 20:1 global average is the figure for new oil, just 5 to 1. It takes a lot of energy to drill five miles under the ocean and pump crude back to a refinery, or to cook tar sands to extract a usable fuel. The energy wellspring at the heart of our economy no longer gushes a torrent of wealth; it’s a smaller, much-diminished stream.
Wind and other renewable energy sources offer returns in the 17 to 1 — still a nice income flow, but nothing like the flood we once got from oil.
Everything our economy accomplishes, including health care, government, schools, roads, defense, repairing our aging infrastructure and re-engineering our built environment to handle the changed weather that oil use has given us, is going to have to be financed from a much-diminished EROEI. And private largess, such as the oil-fueled philanthropy of Andrew Carnegie that built libraries and established foundations and grants for worthy public causes, will fare no better. (The conservative notion that private philanthropy will increase if government takes a smaller bite of the total economy is mostly wishful thinking; the rising overhead costs of energy — the increasing energy cost of energy — will shrink the economic pie as a whole, no matter where we make our slice between the public and private sectors).
Conservatives in Washington and elsewhere insist that we can no longer afford the level of governmental services we’ve become accustomed to. Their call for austerity in public spending is partially right, but for reasons that are wholly wrong: they think that by busting public unions, by reneging on pension agreements for teachers and public employees, by privatizing the production of public goods (streets, schools, even national defense), by cutting regulations and in general shrinking the government, they’ll release the pent-up entrepreneurial energies of business, which will put things back the way they were a few decades ago, when oil was returning a respectable 40:1. That’s simply not going to happen.
Beyond the wrangling between the deficit reducers and the Keynesians, like Paul Krugman, who warn (correctly) that deficit reduction during a recession will only make the recession worse, there lies another deficit, one that no one is talking about: the deficit we’re currently running in our country’s environmental account. We’re drawing down natural capital to cash it out as wealth, which means we’re spending a capital stock — healthy ecosystems — as if it were income. Worse, we borrow money against the prospect of being able to do this forever. That, too, simply isn’t going to happen.
We’ve begun to recognize that we can’t borrow infinitely against our financial future. At some point we have to recognize that we can’t borrow infinitely against our environmental future, either. We’ve got to learn to budget ourselves to the level of economic activity that can be supported and maintained by current solar income instead of running that account in the red. We’ve got to stop counting on continued drawdown of finite stocks of fossil fuel and stop counting on paying our current expenses by borrowing against the continual expansion of our economy’s ecological footprint.
The partisans of Infinite Planet Theory who are managing our (supposedly) infinite growth economy don’t recognize this. They don’t see the shape of the emergent reality: the energy overhead of our economy is increasing at precisely the moment we need even greater investment to build a sustainable, renewable energy society and re-engineer our civil infrastructures to handle the world as we have made it. It’s a very difficult squeeze: needed expenses are rising as income flow declines.
Some room for hope
It is possible to have a decent civilization founded on the rates of return that renewable energy offers — and unlike the EROEI of oil, those rates can be expected to increase with time and technological development. Solving the EROEI squeeze means committing ourselves to building the infrastructure we need to capture current solar income and run our economy on renewable, non-carbon-based energy. Every unit of fossil energy we use to do anything else commits the United States and the planet as a whole to a lower, more straitened standard of living in the future. If we want to see an America of crumbling concrete and weed-filled vacant lots, an America too poor to repair its buildings and bridges, too poor to educate its young to the highest standards, an America that has become a fallen, impoverished power, we need only continue as we are: burning fossil fuel, ignoring climate change, and refusing to invest in the renewable energy infrastructure we need for a sane, rational, steady state economy.
